Application filed February 17, 1908. Serial No. 416,824.

To all whom it may concern:

Be it known that I, IRA. H. SPENCER, a citizen of the United States, anda resident of Hartford, in the county of Hartford and State ofConnecticut, have invented a new and Improved Dust Extractor andSeparator, of which the following is a specification.

My invention relates to the class of devices now more especially knownin the art as suction cleaners, and the object of the invention is toprovide a device of the class named having numerous features ofadvantage and utility.

, A form ofdevice in the use of which the object sought may be attainedis illustrated in the accompanying drawings, in which- Figure 1 is aside view of a machine embodying my invention with parts cut away toshow construction. Fig. 2 is'a view in cross-section through the same onthe line 2.--2 of Fig. 1. Fig. 3 is a view partially in section throughthe device on the line 3-3 of Fig. 1. Fig. 4 is a detail view in sectionon enlarged scale through one of the receiver casings. Fig. 5 is a likeview in central section through the upper part of the stack showing themethod of suspending the separator.

My invention while not limited to any particular kind of apparatus isespecially applicable in that class of suction cleaners in which arotary fan is employed to create a movement of the air current, and forthis reason such an apparatus has been selected by me to illustrate myinvention.

In the accompanying drawings the numeral 5 indicates standardssupporting a receivencasing 6 constructed of any suitable material,preferably sheet metal, and as shown herein preferably round incross-section. These casings each contain receivers 7 which may be inthe formof drawers each having a handle 8 by means of which it may beremoved. These drawers are'co-nstructed to receive material at the top,as shown in Fig. at of the drawings. The standards and casings are ofsuflicientstrength to support the entire apparatus including a motor 9of any approved form of construction.

In some'instances it maybe desirable to support the motor 9 in adifferent manner than as herein shown, and in order to adapt theapparatus to accomplish this result,.and at the same time not employmore parts than i are actually required, the parts herein shown asadapted to support the motor with its shaft in line with the shaft ofthe fans comprising the blower are made removable. To this end the upperpart of the standards 5 are each formed on opposite sides of the easlngs6 W1th bridge seats 10 on which the bridges 11 rest and to which theyare secured as by means of bolts or any other suit-able form ofattachment. These bridges are preferably in the form of arches fittingthe caslngs 6 and on the top of the bridges socket pleces 12 arelocated. Although not essential, in the preferred form of constructionthese bridges are made of cast metal and the socket pieces 12 areintegral therewith. Sockets 13 are formed in each of the socket piecesin which sockets are located bars 14; extending between the bridgesappurtenantto each of the standards 5 and projecting at one end of thestructure to a distance suf- "ficient to receive the motor 9. Clampscrews 15 may be employed to hold the bars in position. A motor support16 is formed at each end with lengthwise openings through which the bars14 extend. These openings are somewhat wider than the bars 14 so thatthe latter may have a movement therein. Ad justing screws 17 and 18extend respectively through the bottom and top of the motor support as ameans of locating the base with respect to the bars and thus provide avertical adjustment of the support for the purpose of alining its motorshaft with the shaft of the blower. Lateral adjustment may be obtainedas by means of bolts extending from the motor support through slots inthe motor base, suit-able nuts being employed for holding the partstogether. It will be seen from this construction that the casingscontaining the receivers may be of comparatively light construction asthe weight of the motor will be received by the bridges and transmittedto the standards 5, thereby relieving the casings from any part whateverof the weight of such motor.

The numeral 19 denotes a blower casing, and by the term blower as usedherein is meant a device for creating flow of a current of air, whetherthe working effects of this be utilized from the intake or from theexhaustend of said blower. In the arrangement of the apparatus hereinillustrated the efi'ective work of the air current is obtained at theintake end of the blower.

Patented Nov. 5, 11912 able length for any special requirement, and

wings 24 located at suitable intervals apart project from the partition22.

An intake 26 to be hereinafter referred to is connected with one of thereceiver casings, in the form of structure herein shownthat casinglocated at the end of the shell next to the blower.

Cleaning devices, referably in the form of tools constructed orapplication to floors,-

walls, carpets, and the like, are connected with the intake 26 by anysuitable means, the fan or blower serving to create a flow of air inwardthrough said intake and thus produce a suction at the mouth of thecleaning tools by means of which dust is conveyed from the floors orfabrics by the current of air passed through the blower.

A plate 27 is located at one end of the shell 19, and on the fan side ofsaid plate a deflector 28 is arranged. This deflector, as shown in Fig.2, extends from the outer edge of the plate in a curved directionapproaching gradually nearer its axial center the farther it extends.The shaft 20 is supported by this plate projecting through it, theopening in which the shaft is located, however, being protected from theentrance of dust so that the plate is practically closed at this point.In fact, in effect it entirely closes this end of the shell except foran opening 29 extending through the plate preferably at the end of thedeflector 28. The deflector is provided at its end with a hood 30 soconstructed that a current of air, and the dust or dirt commingledtherewith passes within this hood and is thereby guided into the opening29. A connecting tube 31 leads from the opening 29 into a chamber 32 ina stack 33. The chamber 32 is located at the lower portion of the stack,its location preferably, and as herein shown, being below the line ofthe axis of the shaft 20, and in the preferred form of construction theopening 29 through the plate is on'the horizontal level of the axis ofthe shaft. The chamber 32 is separated from the upper part of the stackby a wall 34, which wall, however, is of inverted conical shape having afloor or shoulder 35 and a throat 36.

A separator 37 constructed preferably of fabric of comparatively thinmesh is supported within the upper part of the stack 33 and hasat itslower end a weight 38 of ring shape resting upon the floor or shoulder35 to hold the screen or separator in proper position. An outlet 39 islocated atthe top of the stack 33, to which a pipe may be connectedthrough which the air may be delivered to any suitable point.

.The device as herein illustrated and described is particularly compactand the arrangement of the mechanisms for delivering the air from theshell into the stack is such that the latter is not of objectionablelength, extending only a short distance above the shell, and at the sametime the construction is such that the impurities contained within theair will be separated therefrom to a great extent before the air passesthrough the screen or separator 37.

In the machine herein illustrated and described and embodying myinvention in one form, it will be seen that the action of the fanproduces inflow of a current of air at the mouth of the cleaning tools,through the tubing and intake 26, from which it turns upward over thereceiver 7 at the left-hand end of the machine, this deviation of theair current causing the heavier portions of dirt and dust with which theair current is laden to be deposited in said reservoir. The currentpasses through 'the shell under the influence of the fan into thechamber 40. where, by the action of the fan in that chamber it is givena circular motion. The current coming in contact with the deflector 28is directed inward toward the axial center of the shell, encounteringthe hood 30, which causes it to flow through the connecting tube 31,which tube is arranged tangentially to the wall of the circular chamber32, Where it again takes up a circular motion. The threat 36, however,being located below the tube 31, causes the circularly moving current totravel downward and then make an abrupt turn upward through the throat3.6 and within the screen or separator 37. The.

circular movement of the current of air within the chamber 32 causes theheavier portions of dirt or dust to be thrown off by centrifugal force,and the action of gravity causes such portions to drop andbe depositedin the reservoir 7 at the right-hand end of the machine. The aircurrent, by the action of the mechanism, is relieved to a very greatextent, if not wholly of foreign matter as dust or dirt, and what littleremains is removed by the screen 37, so that practically a current offree air passes out through the outlet 39. The deviation of the aircurrent from the chamber 40 to the lower levels of the machine andwithin the chamber 32 enables the screen 37 to be set low, and therebyan extremely short stack may be employed, providing a very compactapparatus.
